There is no current in the shield inner surface, the energy is in the

surface current is insignificant.

this is a pretty amazing revelation. So what are the assumptions to
make this true?

https://en.wikipedia.org/wiki/Transm...#Coaxial_cable

Do you think there is significant current in the walls of a wave guide?

You keep posting the same link which offers nothing to support your
point. So I have to assume you don't have any reason to believe there
is no current flow in the coax.

You keep asking the same question over and over when the answer is
in the link I keep posting.

Obviously you have not read and understood the link.

You keep responding to questions with questions. If you actually
understand this stuff, do you care to explain any of it?


Since you don't seem to be able to deal with the self discovery methhod
of instruction...

There is no significant current in the walls of a wave guide.

There is no significant current in the conductors inside of a coax
transmission line.

That such is true is shown by the equations in the link I have posted
many times now.

Do you see any error in any of those equations?
